I did the 4 row radiator swap and put in a transmission cooler. That's it, and the car has been sitting for about 2 weeks in one place. Here's the symptom:

Put the car in gear, any gear, and it doesn't do anything. No lurching, no movement, nothing.

What could I have disconnected, forgotten to do, etc to make the transmission quit shifting?

The shifting linkage seems to be working. I can see it moving inside the engine bay on the steering shaft, and I can see it shifting on the side of the tranmission (although I'm not sure if it's actually doing much right at the tranny)

All hoses are connected, parking brake off...can't think of any obvious stupid things I could have done.

The radiator is brand new, so that should be okay. It might be the fluid, since I added that more distance to the whole chain..I'm going to try that now, but could that completely stop a tranny from shifting? Kinda weird.
